What is a DisposeBag in RxSwift?


RxSwift: DisposeBag

  • Used to avoid memory leaks as the subscription will not be disposed of correctly without.
  • DisposeBag holds disposables.
  • DisposeBag allows us not to have to dispose of each subscription individually.
  • Used with .addDisposableTo() operator which will call dispose() on each when the dispose bag is about to be deallocated.
let disposeBag = DisposeBag()

Observable.of("Chris Sutton", "Henrik Larsson", "Bobo Balde")
	.subscribe {
  • Can manually cause an observable to terminate by cancelling the subscription to it (Not recommended - should use disposeBag above).
